Low-Carb Bell Peppers

For the Marinara:
 1 tbsp olive oil
 ¼ small red onion, chopped
 1 cup chopped mushrooms
 1 large heirloom tomato, chopped
 ½ cup brown beef stock
 ¼ bunch fresh basil, chopped
 1 tsp garlic powder
 ¼ cup heavy cream
 ¾ cup grated Parmesan cheese (about 2 ounces)
For the Filling:
 1 tbsp coconut oil or MCT oil
 ¼ small white onion, chopped
 3 green onions, chopped
 2 cloves garlic, chopped
 4 oz spinach, chopped
 8 oz 80/20 ground sirloin
 8 oz Italian sausage, casings removed, crumbled
 2 oz cream cheese (¼ cup)
 2 oz feta cheese
 2 tsp Italian seasoning
 ½ tsp kosher salt
 ¼ tsp ground black pepper
 2 tbsp high-fiber coconut flour
 3 tbsp hazelnut flour, divided
 4 small bell peppers, any color, seeded and cored
 1 tbsp ground flax seeds
 ¾ cup grated Parmesan cheese (about 2 ounces)

Preheat the oven to 425°F. Line a sheet pan with parchment paper and set a cooling rack in it.


Make the marinara: Heat the olive oil in a small saucepan over medium heat for 1 to 2 minutes. When the oil is hot, add the red onion and mushrooms to the pan and sauté for 3 to 4 minutes, until the vegetables have begun to brown, stirring occasionally.


Add the tomato to the saucepan and cook for 3 to 4 minutes, then add the stock, basil, and garlic powder. Bring to a boil, then lower the heat and simmer for 15 to 20 minutes, until reduced by one-quarter. Stir in the heavy cream and Parmesan cheese.


While the marinara is simmering, make the filling for the peppers: In a large sauté pan over medium heat, heat the coconut oil for 1 to 2 minutes, then add the onions, garlic, and spinach and sauté, stirring occasionally, for 2 to 3 minutes. Transfer to a small mixing bowl and set aside to cool slightly.


In a large bowl, combine the ground sirloin, sausage, cream cheese, feta cheese, Italian seasoning, salt, and pepper with the spinach mixture and ¼ cup of the marinara; mix to incorporate all the ingredients.


Mix together the coconut flour and 1 tablespoon of the hazelnut flour, then evenly dust the inside of each bell pepper with the flour mixture. Stuff each pepper evenly with about 5 ounces of the filling and set on the cooling rack in the prepared sheet pan.


Combine the remaining 2 tablespoons of hazelnut flour, ground flax seeds, and Parmesan cheese in a small bowl, then evenly dust the tops of the stuffed bell peppers.


Bake for 18 to 20 minutes, until the internal temperature of the filling, reaches 155°F. Remove from the oven, plate with the remaining marinara, and serve your low-carb bell peppers immediately.


Store leftover low-carb bell peppers in an airtight container in the refrigerator for up to 4 days.
